ADJUSTABLE- HOOD FOR COOKING-STOVES.

SPECIFICATION forming part of Letters Patent No. 369,161, dated August 30, 1887. Application tiled March 3, 1887. Serial No. 229,538. (No model.)

To @ZZ whom, it may concern:

Beit known that I, GOTERID CARLSON, a subject of the King of Sweden and Norway, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a certain new, useful, and Improved Adjustable Hood for CookingStoves, of which the following is a description, reference being had to the accompanying drawings, forming a part of this specification, in which-- Figurel is a side view of a cookingstove to which my adjustable hood is applied. Fig. 2 shows plan, face, spcctively, of a clamp for engaging the adjusting-rod. Fig. 3 shows sectional, side, and face views, respectively, of a portion of the adjusting-rod. Fig. elE` embraces plan and face views, respectively, of the bracket which sustains the hood against the stove-pipe; and Fig. 5 shows a side view in detail of a portion of the adj listing-rod and locking device, and also a plan view of the same partly in section.

Like letters of reference indicate like parts in the different figures. Y

The object of my invention is to provide a hood for cooking-stoves and ranges, which may be raised and lowered at will and adjusted to any desired height, all of which I accomplish substantially in the manner hereinafter more particularly described and claimed.

A in the drawings represents an ordinary cooking-stove having a pipe, B, connected therewith and arranged in the usual manner. Attached thereto is a smaller horizontal pipe, C, having an elbow, D, attached to and depending therefrom. Rigidly secured to said elbow is a vertical section of pipe, E, to which are in turn loosely connected two or more telescoping pipe-sections, F G, to the bottomof the latter of which is secured a hood, H.

The pipes C E are maintained in place and prevented from sagging by means of a bracket, J, riveted thereto and to the pipe B. A cord, K, attachedto an eye, K', trained over a pulley, K2, secured to the bracket and having a weight, K3, attached to its opposite end, is preferably employed to balance the weight of the hood H. A casting having a face-plate, H', and curved portion H2, (shown in detail in Fig. 4,) is rigidly attached to said hood, so

and sectional side views, re-l A pin or screw, m, upon the lower end of the I rod and above the lowcrmost bracket serves to keep said rod in place. The lower end of the rod is bent outwardly, as at L3, and forms a handle foruse in its adjustment. The lower bracket L is cut away at Z, Fig. 5, upon which face the pin m rests, the lateral movement of the rod being limited thereby to a quarter of a revolution, as indicated in dotted lines in said Fig. 5. The resiliency of the rod serves to keep the notches m in engagement with the hook L2; but, in view of the direction of the slant given to said notches, it is evident that therod may be readily pushed upwardly, and with it the hood H, the sections E F G telescoping each other. Upon turning said handle in the direction represented by the arrow shown in Fig. 5, the smooth side of the rod is presented to the hook L2, whichpermits the hook to be drawn downwardly to any desired extent.

The advantage of said adjustable feature is that the hood may be lowered sufficiently to insure the removal of all of the smoke and vapors when the operative is not actually working over the stove, while at other times it may be more or less elevated, as desired, or raised entirely out of the way. A damper, O, Fig. l, is preferably inserted in the pipe, to be closed when the hood is not required.

It is evident that if the hood be perfectly balanced by means of the cou nterpoise-weight, the rod M may be dispensed with, but I prefer to use the latter, as it insures more satisfactory results. Said rod may be used without the counterpoise, if desired. It vis also apparent that the Ventilating-pipe may be connected directly with a chimney line or other Ventilating-opening.

Having thus described iny invention, what I eiairn, and desire to secure by Letters Patent, 1s-- The combination, with a cooking-stove and pipe, of a hood, a series 0f telesooping pipes connecting with said hood, intermediate pipe, C, and means, as the bracket J, for supporting,` the saine in a horizontal position, a oord 'and pulley attached to said bracket for baiguide-bracket H2, and ro
